Description
Die Erfindung betrifft einen Feststeller zwischen zwei relativ zueinander beweglichen
Objekten entsprechend dem Oberbegriff von Patentanspruch 1.The invention relates to a lock between two movable relative to each other
Objects according to the preamble of
Aus der DE 15 29 716 A1 ist ein hydropneumatisches Hubaggregat mit einer hydraulischen Sperre bekannt. Das Hubaggregat verfügt über einen Arbeitsraum, in dem ein Arbeitskolben eine Betriebsbewegung ausführen kann. Zwischen dem Arbeitskolben und der Wandung, die den Arbeitsraum begrenzt, ist ein willkürlich ansteuerbares Reibelement angeordnet, dessen Reibkraft durch einen Volumenzuwachs erzeugt wird. Der Volumenzuwachs wird durch Zuführen von hydraulischem Medium in das elastisch aufweitbare, als Hohlkörper ausgeführte Reibelement erreicht.DE 15 29 716 A1 describes a hydropneumatic lifting unit with a known hydraulic lock. The lifting unit has a work area, in which a working piston can perform an operating movement. Between the Working piston and the wall that limits the working space is an arbitrary controllable friction element arranged, the frictional force due to an increase in volume is produced. The volume increase is achieved by adding hydraulic Medium in the elastically expandable, designed as a hollow body friction element reached.
Die DE 199 10 782 A1 beschreibt ein Türscharnier, der einen Zylinder aufweist, der mit einer elektrorheologischen Flüssigkeit gefüllt ist. Ein als Flügel ausgeformter Kolben unterteilt den Zylinder in mindestens zwei Arbeitsräume. Eine Strömungsverbindung zwischen den Arbeitsräumen unterliegt dem Einfluss eines elektrischen Feldes, so dass durch Änderung der Viskosität der Flüssigkeit innerhalb der Strömungsverbindung eine Blockierwirkung erreicht wird. Die Haltekraft des Türfeststellers kann dadurch gesteigert werden, dass man die Strömungsverbindung möglichst lang dimensioniert. Eine derartige Ausgestaltung begrenzt jedoch den maximalen Schwenkwinkel des Türscharniers, da die Strömungsverbindung von einem Spalt zwischen dem Flügel und der Wandung des Zylinders gebildet wird.DE 199 10 782 A1 describes a door hinge that has a cylinder, which is filled with an electrorheological fluid. A wing shaped Piston divides the cylinder into at least two working spaces. A flow connection between the work rooms is subject to the influence of an electrical Field, so by changing the viscosity of the liquid within a blocking effect is achieved in the flow connection. The holding power of the door arrester can be increased by changing the flow connection dimensioned as long as possible. However, such a configuration limits the maximum swivel angle of the door hinge since the flow connection formed by a gap between the wing and the wall of the cylinder becomes.
Aufgabe der vorliegenden Erfindung ist es, einen Feststeller zwischen zwei relativ zueinander beweglichen Objekten zu schaffen, der einen sehr einfachen Aufbau aufweist und wenig Bauraum benötigt.The object of the present invention is to determine a relative between two to create mutually movable objects of a very simple structure has and requires little space.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Reibelement mit einer elektrischen Spannungsversorgungseinrichtung verbunden ist, wobei in Abhängigkeit der angelegten Spannung eine Volumenveränderung des Reibelementes auftritt, die eine Stellbewegung des Reibelementes bezogen auf die Reibfläche darstellt.According to the invention the object is achieved in that the friction element an electrical voltage supply device is connected, depending a change in volume of the friction element of the applied voltage occurs, the adjusting movement of the friction element based on the friction surface represents.
Eine besondere Eigenart des Feststellers ist darin zu sehen, dass man ohne Blockierventile o. ä. teilweise aufwändigen Baugruppen auskommt und trotzdem eine stufenlose Arbeitsweise bezogen auf den Betriebsweg des Feststellers nutzen kann.A special peculiarity of the lock is to be seen in the fact that one without blocking valves or the like sometimes requires complex assemblies and still one use stepless operation in relation to the operating path of the lock can.
Neben der Möglichkeit einen Piezo-Aktuator zu verwenden ist vorgesehen, dass das Reibelement von einem Kohlenstoff-Aktuator gebildet wird.In addition to the possibility of using a piezo actuator, it is provided that the friction element is formed by a carbon actuator.
Es gibt wiederum mehrere Möglichkeiten bezüglich des Aufbaus des Kohlenstoff-Aktuators. So kann der Kohlenstoff-Aktuator aus Fullerenen bestehen. Fullerene verfügen über eine polyederförmige Gestalt. Alternativ kann der Kohlenstoff-Aktuator auch in der Form von zusammengefassten Röhrchen ausgeführt sein. Again, there are several options regarding the construction of the carbon actuator. The carbon actuator can thus consist of fullerenes. fullerenes have a polyhedral shape. Alternatively, the carbon actuator also be designed in the form of combined tubes.
Die Röhrchen wiederum können zu einem gut handhabbaren Flies, ähnlich wie Papier, zusammengefasst sein.The tubes can turn into a manageable tile, similar to Paper, be summarized.
Zur Steigerung der Reibwirkung und zum Schutz kann der Kohlenstoff-Aktuator mit einem Reibbelag beschichtet sein.The carbon actuator can be used to increase the friction effect and for protection be coated with a friction lining.
Eine besonders einfache elektrische Kontaktierung erreicht man insbesondere dann, wenn der Kohlenstoff-Aktuator zumindest teilweise von einem Elektrolyten eingeschlossen ist.A particularly simple electrical contact is achieved in particular then when the carbon actuator is at least partially from an electrolyte is included.
Als Elektrolyt kann z. B. eine ganz einfache Salzlösung verwendet werden.As an electrolyte z. B. a very simple salt solution can be used.
Als besonders vorteilhaft hat es sich herausgestellt, wenn der Feststeller als Drehscharnier ausgeführt ist und der Reibflächenträger von einem Scharnierbolzen gebildet wird. Man erreicht ein sehr günstiges Verhältnis von der Größe der Reibfläche zur räumlichen Ausdehnung des Zylinders.It has turned out to be particularly advantageous if the ascer Swivel hinge is executed and the friction surface carrier by a hinge pin is formed. You get a very good ratio of the size of the Friction surface for the spatial expansion of the cylinder.
Um einen möglichst kompakten Aufbau zu erreichen, weist der Scharnierbolzen einen Flansch auf, der für das Drehscharnier einen Deckel bildet.In order to achieve the most compact possible construction, the hinge pin has a flange that forms a lid for the rotary hinge.
Optional kann der Feststeller mit einer Sensorik bestückt sein, die eine Relativbewegung der beiden zueinander beweglichen Objekte erfasst. Mit der Sensorik kann eine Steuerung des Feststellers vorgenommen werden.Optionally, the arrester can be equipped with a sensor system that has a relative movement of the two mutually moving objects. With the sensors the lock can be controlled.
In weiterer vorteilhafter Ausgestaltung weist die Sensorik ein Getriebe mit einem Ein- und mit einem Ausgangsteil auf, wobei eine der beiden Getriebeteile mit dem Reibflächenträger und das andere mit dem Zylinder in Wirkverbindung steht. Mit dem Getriebe kann eine Spreizung der Sensorik erreicht und damit die Genauigkeit gesteigert werden. In a further advantageous embodiment, the sensor system has a transmission with a In and with an output part, with one of the two transmission parts with the The friction surface carrier and the other are operatively connected to the cylinder. With the transmission can spread the sensors and thus the accuracy be increased.
Dabei ist der Flansch des Scharnierbolzens als ein Getriebeteil ausgeführt und der Zylinder weist eine exzentrisch zur Mittelachse des Feststellers ausgeführte Lagerstelle für das andere Getriebeteil auf. Anbauten für die Sensorik an den beiden zu einander beweglichen Objekten können entfallen.The flange of the hinge pin is designed as a gear part and the Cylinder has a bearing point that is eccentric to the central axis of the arrester for the other gear part. Attachments for the sensors on the two objects moving towards each other can be omitted.
Um möglichst auf eine lange Betriebszeit und unter allen Umständen möglichst genau und zuverlässig zu funktionieren, ist das Getriebe der Sensorik als ein Zahnradgetriebe ausgeführt.To as long as possible and under all circumstances if possible To function accurately and reliably, the transmission of the sensors is as one Gear transmission executed.
Anhand der folgenden Figurenbeschreibung soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the following description of the figures become.

Die Figuren 1 - 3 zeigen einen Feststeller 1, wie er beispielsweise zwischen einer
nicht dargestellten Fahrzeugkarosserie und einer Fahrzeugtür verwendet werden
könnte, wobei die Fahrzeugtür ein bewegliches Objekt darstellt. Der Feststeller
umfasst einen Zylinder 3, in dem ein Reibflächenträger 5 angeordnet ist. Beide
Hauptkomponenten sind mit Anschlussorganen 7; 9 versehen zu jeweils einem
der genannten Objekte. Der Reibflächenträger 5 und der Zylinder 3 bilden einen
Ringraum 11, in dem ein Aktuator 13 mit einer spannungsabhängigen Volumenveränderung
angeordnet ist. Konstruktiv ist der Feststeller als ein Drehscharnier
ausgeführt, wobei der Reibflächenträger 5 von einem Scharnierbolzen gebildet
wird, in dem die Mantelfläche des Scharnierbolzens die Reibfläche 15 darstellt.Figures 1-3 show a
Der Aktuator besteht aus einem zumindest kohlenstoffhaltigen Werkstoff, der in
seiner Struktur Fullerene oder Röhrchen aufweist, die zu einem Flies zusammengefasst
sind. Das Rohmaterial wird unter der Bezeichnung Bucky-Paper oder Bucky-Balls
vertrieben. Zur Übertragung der elektrischen Spannung von einer elektrischen
Spannungsversorgungseinrichtung 16, beispielsweise der Fahrzeugbatterie,
auf den Aktuator ist der Ringraum 11 zumindest teilweise mit einem Elektrolyt,
z. B. einer einfachen Kochsalzlösung gefüllt. Ein Flansch 17 des Scharnierbolzens
5 als Deckel und eine Isolierscheibe 19 begrenzen den Ringraum 11, wobei
zusätzliche endseitige Dichtungen 21; 23 einem Verlust des Elektrolyts entgegenwirken.The actuator consists of an at least carbon-containing material, which in
its structure has fullerenes or tubes that are combined into a fleece
are. The raw material is called Bucky Paper or Bucky Balls
distributed. To transmit the electrical voltage from an electrical
Sobald über nicht dargestellte elektrische Anschlüsse am Feststeller zum Kohlenstoff-Aktuator
eine elektrische Spannung gelegt wird, dehnt sich dieser räumlich
aus und stellt einen Kontakt zur Innenwandung des Zylinders und der Reibfläche
15 her. Dabei wird über den Kohlenstoff-Aktuator als Reibelement selbst ein
Reibschluss zwischen der Innenwandung und dem Scharnierbolzen hergestellt,
die einer Haltekraft zwischen der besagten Fahrzeugtür und der Fahrzeugkarosserie
entspricht. Zur Steigerung der Reibkraft und Erhöhung der Lebensdauer kann
das Flies auch mit einem Reibbelag beschichtet sein, der nicht isolierend wirkt.As soon as via electrical connections (not shown) on the brake to the carbon actuator
an electrical voltage is applied, this expands spatially
and makes contact with the inner wall of the cylinder and the
Optional verfügt der Feststeller über eine Sensorik 25, die eine Relativbewegung
der beiden zueinander beweglichen Objekte, also der Fahrzeugtür zur Fahrzeugkarosserie,
erfassen soll. Die Sensorik besteht aus einem Signalgeber 27, in diesem
Fall einer drehbaren Scheibe mit Positions-Codes und einem dazu ortsfesten Signalaufnehmer
29, z. B. einer Photozelle. Die Scheibe 27 ist exzentrisch achsparallel
zur Mittelachse des Feststellers 1 mittels einer Welle 31 innerhalb des Zylinders
3 gelagert und wird über ein Getriebe bei einer Relativbewegung innerhalb
des Feststellers angesteuert. So ist der Flansch 17 des Scharnierbolzens 5 an
seiner Mantelfläche als Zahnrad 33 ausgeformt und treibt damit die ebenfalls mit
einem Zahnradprofil 35 versehene Welle 31 der Scheibe 27 an. Die beiden Zahnräder
33; 35 stellen jeweils ein Ein- und ein Ausgangsteil des besagten Getriebes
dar. Mit dem Getriebe 33; 35 wird die Drehbewegung innerhalb des Feststellers
durch das Übersetzungsverhältnis des Getriebes gespreizt und die Messgenauigkeit
der Sensorik 25 vergrößert. Ziel der Sensorik ist es, bei einer äußeren Kraft
auf das bewegliche Objekt, die größer ist als eine vorbestimmte Auslösekraft,
diese als eine gewollte Betätigungskraft zu erkennen und die Freischaltung des
Feststellers einzuleiten.Optionally, the arrester has a
